Odontogenic Cyst Case Study

ABSTRACT
Odontogenic keratocyst is the common cyst of odontogenic origin, which draws the attention because of its peculiarity. Now the lesion is renamed as Keratocystic odontogenic tumour (KCOT) because of its neoplastic nature and its tendency to recur. KCOT occurs most commonly in the mandibular ramus area. Maxillary anterior region is a rare site of occurrence. We present a rare case of maxillary KCOT with its clinical features, radiographic and histopathological and surgical management.

Introduction
Odontogenic keratocyst is an odontogenic developmental cyst arising from the dental lamina. Being first described by Phillipsen in 1956, the lesion derives attention by its rapid growth, aggressiveness,

Within the mandible they are found most commonly at the angle of the mandible and often extend into the ascending ramus and the body of the mandible. [5,6]
Here we present a rare case of maxillary Keratocystic odontogenic

The reclassification was due to the special features like enhanced mitotic rate, epithelial budding of basal layer or daughter cysts, chromatid aberrations, PTCH gene mutation. [7,8,9,10,11,12]
Studies have shown that Keratocystic odontogenic tumour is more commonly seen in the mandible compared to maxilla (75.58%) with primary site being posterior ramus area followed by the anterior region. Maxillary lesions show predilection to 3rd molar area followed by cuspid. In the above reported case the lesion was in the maxilla extending from the canine to molar area which is a rare site of occurrence. [5, 6, 13, 14] Although it can occur at any age, significant predilection is in second to third decade of life more commonly in male patients. The above patient was reported in the 4th decade of life which is relatively rare age of occurrence.[15]
Keratocystic odontogenic tumour usually tends to enlarge without significant expansion. [16] However this case showed significant buccal and lingual cortical expansion, which is a rare finding. Other features are swelling, pain, discharge and paresthesia of lip. [17] Our case reported as painless swelling without any discharge or
